Problems solved by technology

This patent document is an improvement on the existing closed rubber ring with a handle. The external high-pressure inflator applies pressure to the blocked pipeline through the hollow handle to realize the dredging of the pipeline. The disadvantage of this patent document is that the high-pressure gas is controlled by human factors. Difficult to grasp, affecting the dredging effect of the pipeline

Embodiment 1

[0037] see figure 1 , the device includes a pipeline equipped with a pressure gauge 3, one end of the pipeline is an air outlet and a water outlet, the other end of the pipeline is connected in parallel with the branch pipe 5, and the other end of the pipeline and the branch pipe 5 are respectively provided with an air inlet valve 6 and a The water inlet valve 4, the other end of the pipeline is communicated with the external inflation device, and the branch pipe 5 is connected with the water source. This device is the most basic device for dredging and leak detection. When dredging the pipeline, connect the hand-push high-pressure gas cylinder at one end of the air inlet or replace the joint with the air pump to inject high-pressure gas, and the gas outlet and water outlet can be directly connected to the part that needs to be dredged. Unclog; when detecting leaks in pipelines, one end of the air outlet and water outlet is connected to the target pipeline, open the water pipe...

Embodiment 2

[0039] see figure 2 , this device is to add a gas tank 2 on the pipeline, and install an exhaust and drain valve 1 between the gas tank 2 and the gas outlet, which can store a certain amount of gas. When not in use, close the exhaust and drain valve 1 to input stable Pressure is very effective for dredging the pipelines that are difficult to dredge, and the setting of the gas tank 2 can use the gas in the gas tank 2 to dredge without having to carry the gas cylinder with you. It is suitable for occasions where there is no gas source or no gas cylinder. Convenient; when used as a measuring device, only the gas tank 2 needs to be removed.

Embodiment 3

[0041] see image 3 , the other end of the pipeline is divided into a first intake pipe 9 and a second intake pipe 7, and an intake valve 6 is installed on the first intake pipe 9 and the second intake pipe 7, wherein the first The air inlet place of an air intake pipe 9 is connected with the air pump joint 10 that joins with air pump, and the air inlet place of the second branch air inlet pipe 7 is connected with the air cylinder connector 8 that joins with manual air cylinder. The other end of the pipeline is divided into two branches, which are respectively connected with the air pump joint 10 and the air cylinder joint 8, and can be directly connected to the air pump or the air cylinder according to the situation without changing the joints. Both are connected by flexible hoses, which is flexible and convenient.

Abstract

The invention discloses a pipeline dredging and leakage-detecting device and relates to the technical field of pipeline dredging devices. The pipeline dredging and leakage-detecting device comprises a pipeline, wherein a pressure gauge is installed on the pipeline, one end of the pipeline is provided with an air-water outlet, the other end of the pipeline is connected with a branch pipe in parallel, the air-inlet valve and the water-inlet valve is respectively arranged at the other end of the pipeline and the branch pipe, the other end of the pipeline is communicated with an external air-charging device, and the branch pipe is connected with a water source. The device has the advantages of simple structure and convenience in use, the pipeline dredging effect can be greatly improved, and the device can be applied to the leakage-testing operation of water pipes and caliducts, particularly floor heating pipes and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging devices. Background technique [0002] At present, all kinds of water, heating, and gas pipelines are as common as the Internet, becoming an indispensable channel in people's lives. The popularity of pipelines brings convenience to people's lives, but also brings some problems. Among them, the blockage of pipelines Difficulty in dredging after blockage is the most common problem. [0003] The existing household small dredger is a closed rubber ring with a handle, which uses the small negative pressure generated between the closed rubber bowl and the blocked pipe to realize the dredging of the pipe. This method is not only time-consuming and laborious, but also the effect is not ideal. , and the rubber is particularly easy to age and break, and the use time is short. [0004] A patent document is retrieved, the name is: pipe dredge; the authorized announcement number is: CN203346974U. ...
